Large volume of wastewater is generated by tannery industry, which contains heavy metals such as Chromium, Cadmium, Lead, Copper, Zinc, Mercury and Arsenic. Chromium (Cr) is one of the common and toxic heavy metal pollutants released by industries in their effluent. In this study, tannery effluent was collected from Challawa industrial estate, Kano, Nigeria. Physico-chemical parameters of the effluent were determined; two fungal isolates Aspergillus terreus and Aspergillus fumigatus were obtained from the wastewater. The industrial effluent was supplemented with minimal salts medium: 3 mg/L NH4Cl, 3 mg/L K2HPO4, 5 mg/L KH2PO4, 1 mg/L NaCl, 1mg/L MgSO4 and tyndallized. The Cr content in effluent were measured before inoculation of the fungal isolates and after using Atomic Absorption Spectrophotometer (Model GBC 932). The co-isolates were found to absorb 97.32% of Cr in the effluent. Scan Electron Microscopy (SEM) was also carried out. Bioremediation is an eco-friendly and economically feasible process.
